UNITED STATES IVER J. RIDER, OF PORTLAND, OREGON.

RADIATOR CA1.

Application filed November 19, 1923.

To all whom it may concern:

Be it known that I, IVER JAMns RIDER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Radiator Caps, of which the following is a specification.

The object of this invention is to provide a cap for the radiator of an automobile engine, which will not only close the threaded inlet connection or neck portion, but which will also provide for the display of a sign of any desired character, or will show the name of the city or State from which the motorist comes.

A further object is to provide in modified forms, signs or name plates adapted to be secured to the cap, or to be held in position by screwing said cap down on the elements specified and on the inlet connection.

\Vith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements.

described, illustrated and claimed, it being understood that modifications may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings, Figure 1 is an elevation of the device, mounted on a radiator; Figure 2 is a fragmentary View, in elevation, portions being broken away; Figure 3 is a section on line 33 of Figure 1; Figure 4 is a view of an illuminated casing, chiefly in elevation, but with a portion broken away; Figure 5 is a section on line 55 of Figure 4:; Figure (3 is a section on line 66 of F igure 1; Figure 7 is a vertical section showing a special form of connecting means between the sign and cap; Figure 8 shows this arrangement in elevation and vertical section; Figure 9 is a fragmentary view of an externally threaded cap or plug; Figures 10 and 11, in top plan and elevation, respectively, show a sign having a ring member adapted to fit an inlet connection and to be held by the cap.

The threaded inlet connection of a radiator is designated 10, and a combined cap and name plate, or sign, is shown at 12. This element 12 may be ten or twelve inches long, and in the present instance is shown as being formed with raised letters showing the name of an important city and adapted to project from the cap in pennant form.

The bar or plate 12 extends in a horizontal position when mounted, the major portion Serial No. 675,701.

played is carried on opposite sides of a casing 11, two inches or less in cross section, and having transparent walls, the casing being adapted to be illuminated by small electric lamps 15. Projecting within the easing is a threaded sleeve 16, closed at its upper end and open at the lower end, and

therefore adapted to be screwed over element 10, in substantially the same position as in the form first described.

It will be observed that element 16 is formed integrally with the casing and projects thereinto, and that the cuplike form prevents vapor from entering the casing. More definitely element 16 forms an inverted cup.

In another form a separate plate 13 is secured to a standard type of cap 13.

In a further form (Figure 9), I have shown a plate 12 having formed therewith an enlargement 17 threaded and adapted to be screwed into an internally threaded neck.

The element carrying the display matter may however have formed thereon an annular internally threaded member or plain ring member 19 proportioned to fit the inlet connection 10, and to be surmounted by a radiator cap of normal or usual construction or form. In the views showing this arrangement (Figures 10 and 11), the plate adapted to carry the letters is designated 12. This is one of the most inexpensive forms, as the ring portion may be cut from the same flat plate of sheet metal as element 12, and a twist formed at 19 in order that the ring portion and plate may be perpendicular to each other.

What I claim is:

A sign formed as a casing, means for illuminating the casing, and an internally threaded element formed as an inverted cup, integral with the casing, and projecting thereinto, for engagement with the threaded inlet connection of a radiator.

In testimony whereof I ailix my signature.

IVER J. RIDER.
